>"I originally wrote gtk which included the three
libraries, libglib, libgdk and libgtk. It featured a flat
widget hierarchy. That is, you couldn't derive a new widget
from an existing one. And it contained a more standard
callback mechanism instead of the signal mechanism now present
in gtk+. The + was added to distinguish between the original
version of gtk and the new version. You can think of it as
being an enhancement to the original gtk that adds object
oriented features."</SPAN

>Although much has changed with GTK+, and Peter, Spencer and Josh
don't have any direct involvement these days, the name is kept to keep
a link with the heritage of GTK+.</P

>GTK+ is now additionally based upon the Pango and ATK
libraries, that provide text layout and rendering and accessibility
interfaces.</P
